Today is a Tokyo holiday, SGX & Osaka Nikkei contact is closed. Good Friday is not considered as a Japanese hoilday therefore the market is open, business as usual.
No doubt Good Friday is a holiday in Singapore. SGX Nikkei is open for business as usual similarly Msci Taiwan contact too is open as it is not a public holiday in their respective countries.
I use the GL brokernet, it is quite okay except at home,there was a few hiccups probably due the wireless network
